HORN EQRx'fALKING-MACHINES.

Patented Dec. 17, 1907 ii iipaion and May 5.1906. semi No. 315.272.

T 0 all whom it may concern:

Be it knownthatyl, ADoLPII G. Sorsr- MANN, a citizen ofth'e United States, residing at Philadelphia,=in the county of Philadelphia and State'of Pennsylvania, have invented. a new and useful Horn for Talking- Machines, ofwhich the following is a specification.

'My invention relates to improvements in horns for talking machines.

My object is to provide an improved structure combining simplicity of construction. strength, and lightness in weight, and tone qualities capable of producing a maximum resonance.

Referring to the drawings: Figure 1 is a side elevation of my horn. Fig. 2 is a longitudinal vertical section thereof, and Fig. 3 isa cross section on line 3, 3 ofsFig. 2, on anenlarged scale.

Similar numerals refer to similar parts throughout the several views. 1

My improved horn conun'iscs a;series'of' non-metallic tapered sections 4, preferably of hard wood or fiber. These sections 4 are each beveled upon each longitudinal edge 5 and 6, as clearly shown in Fig. 3, so that one bevel of each section maybe termed an upper bevel, and the other. an under bevel. These bevels are so disposed that the abutting edges of adjacent sections will overlap. These overlapping edges may be glued or otherwise fastened together to form a continuous horn shaped structure. Upon this structure, l then wrap a very thin narrow strip or ribbon 7 of wood or other suitable material and glue the same securely to said structure. I. have found for example that a ribbon of ,veneering of aiproximately one quarter of an inch in width, and about one twentieth of an inch in thickness makes a satisfactory wrapping. This wrapping extends spirally from one end of a horn to the other. When the structure is so formed and wrapped, the

flaring end thereof is securedinthe ann'ular channel, 8 of the rim or ring 9i This ring or rim 9 has its ends provided'with long bevels 10 and 11, adapted to overlap each other, so

* that, when the flaring-end, of the horn structure is seated in the channel 8, the ring is slightly contracte'd,'the beveled edges 10 and 11 sliding slightly over each other, sothat the rim 9 will form a tight locking engagement with the flaring end of the body of the horn structure.

By the; construction above described, there is ,fbrmed, at minimum expense, a structure having its component parts so intimate and secure, and locked together, as to constitute a substantially integral whole of great strength, extremely light in weight, and having qualities of resonance which render it an extremely powerful and eflicient horn for the purpose specified.

hat -1 claim is 1. A horn composed of longitudinally extending tapered sections forming a structure contracted at one end and flaring at the other, and a thin band spirally wound about.

said structure.

2. A horn composed of longitudinally extending tapered sections, form mg a structure contracted at one -end and flaring at the other, a thin hand spirally wound about said structure, and a ring member provided with an annular channel to. receive the flaring end of said structure.

3. A horn composed of longitudinally extending tapered sections, forming a structure contracted at one end and flaring at the other, and a reinforcing band surrounding thel body of the horn intermediate its two cm s.
